Distance Vector Multicast Routing Protocol
The Distance Vector Multicast Routing Protocol (DVMRP) is a routing protocol designed for multicast networks. It uses a distance vector algorithm to determine the best path for data packets to travel from a source to multiple destinations. DVMRP builds a multicast distribution tree, allowing efficient data transmission to multiple receivers without sending duplicate packets.
DVMRP operates by exchanging routing information between neighboring routers, which helps them learn about the network topology. It supports features like reverse path forwarding and pruning, which optimize the multicast traffic flow. This protocol is commonly used in conjunction with other protocols like Internet Group Management Protocol (IGMP) for managing multicast group memberships.
